In many ways, Forstall is a mini-Steve. He’s a hard-driving manager who obsesses over every detail. He has Jobs’s knack for translating technical, feature-set jargon into plain English. He’s known to have a taste for the Mercedes-Benz SL55 AMG, in silver, the same car Jobs drove, and even has a signature on-stage costume: black shoes, jeans, and a black zippered sweater. (He favors Reyn Spooner Hawaiian shirts for normal days at the office.)
